In front of an absolutely packed room in Monterey, the gavel finally came down on RM Sotheby’s big sale this year—a 1962 Ferrari 250 GTO—to the tune of $48.4M. Now officially the most expensive car ever sold at auction, 250 GTO chassis no. 3413 adds a new notch to its belt, alongside an illustrious racing history that included nine wins in 1962 and a run at the Targa Florio with famed driver Phil Hill behind the wheel.
